the set of rolls from slipping while being Wound in a paper winding machine.

It is particularly aimed to provide a construction using a novel collar adjustable on a sleeve` mounted by a winder shaft, for engagement b-y the paper at one edge while being wound.

It is `further aimed to provide a construction wherein the collar is capable of movement in one direction only namely toward the paper edge and which has a ratchet connection along the mounting sleeve and means whereby the connection may be released when desired.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection withv accompanying drawings illustrating an operative embodiment.

. In said drawings:

Figure 1 is a view partly in elevation and partly in section, showing the use of my invention in connection with the Winder shaft in a paper winding machine;

Figure 2 is an enlarged view primarily in central longitudinal section showing the collar, its mounting and association with the winder shaft and paper roll;

Figure 3 is an edge elevation of the collar;

Figure 4 is a detail section taken on the line 4-4 of Figure 3;

Figure 7 is a view similar to Figure 5 of a modified form;

Figure 8 is a diametric section takencn the line 8 8 of Figure 7;

Figure 10 .is an edge elevation of the form of ring or collar of Figure 9;

Figure l1 is a section taken on the plane of line II-I I of Figure 10;

Figure 12 is a section taken on the plane of line I2-I 2 of Figure 9, and

Figure 13 is a detail section taken on the line Iii-I3 of Figure 9.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, I0 designates a conventional Winder shaft of a paper winding machine in connection with which a removable core II constituting usual equipment, is used, and upon which a roll of paper or the equivalent I2 is wound through the operation of the machine.

In carrying out my invention, a sleeve I3 is removably disposed upon the shaft IB with one end in abutment with the core and adjacent which end, sleeve I3 is peripherally grooved as at I4, to provide ratchet rings or teeth I5. Such Sleeve I3 is suitably positioned through the aid of sleeves I6 of any desired number, placed end to end in contact with each other and with the sleeve I3 and held in place by a nut Il engaged with screw threads I8 of the Winder shaft l0.

Applicable over the sleeves I3 and I6 is a removable ring or collar I9, whose bore is smooth so that it may slide over the ratchet teeth or rings at I5. Such collar I9 has radial openings at 20 in which dogs 2I are slidably disposed to engage the grooves I4 and hold the collar in abutment with the paper I2 at one edge. Such dogs are chamfered at 22 at their inner edges longitudinally so as to fit the grooves I4 and they are concave circumferentially as shown at 23, to better conform to the periphery of sleeve I3 at the grooves I4. Such dogs 2I may be of any desired shape in cross section. Due to the particularshaping of the teeth and the grooves I4 and ratchet teeth I5, it will be clear that the collar I9 is capable of movement only from left to right in Figures 1 and 2 and thus cannot be moved from right to left in such figures. Also, the inner ends of some of the dogs may be cut away as at 24, so that the dogs will engage the ratchet teeth some before others, and thus giving a more graduated adjustment on the sleeve I3. As particularly shown in the first form of the invention, the dogs may be rectangular in cross section.

Disposed peripherally of the ring or collar I9, are spring blades 25 of arcuate formation, fastened to the collar as by means of screws 26 and having their free ends outwardly deflected as at 21. Dogs 2| are suspended in the recesses 20 by the springs 25 by means of screw elements 28 engagingv the dogs, passing through the springs and having heads at 29, whereby they may be engaged to manually retract the dogs if desired. Any ratcheting action of the dogs over the teeth I5, will be against the tension of the springs 25 as will be understood.

The periphery of the collar is recessed as at 3U and has an annular groove at 3l, in communication with the recesses. The springs 25 are accommodated in the recesses and a ring 32, preferably externally knurled, as Shown, is rotatably mounted in the groove 3l and at the points of connection between groove 3| and recesses 30,

cam members 3|', are disposed. Such cam members consist of triangular portions 32 and lugs 33 riveted at 34 to the ring 32. As a result of the construction described, the ring 32 may be partially rotated whereby the cams 3| move under the deflected ends 21, thereby lifting springs at such ends and lifting or retracting the dogs 2I so that they disengage the grooves I4 and ratchet teeth I5.

It will be understood that the sleeve I3 and coacting collar I9 and associated parts may be used at both ends of the paper roll I2, if desired, and that if desired, one of the collars need not be provided with the ring 32 and the cam members 3I as it is necessary to remove but one of the collars I9, in removing the roll I2 from the machine.

Various changes may be resorted to provided they fall within the spirit and scope of the invention. For instance I may use the modified form of Figures '1 and 8. In such form, the dogs 2Ia function like those at 2I but are preferably cylindrical in form. They are mounted by springs 25a but in lieu of the fastening 28-29, the springs 25 pass removably through undercut slots provided in the upper ends of the dogs 2Ia. In all other respects, the modified form of Figures 1 and 8 corresponds to that of the first form of the invention. It is clear that any desired number of the dogs may be used in any form of the invention.

Another form or modification is shown in Figures 9 to 13. Here, the ring 32b functions like that at 32 but is preferably made up of arcuate sections 36, overlapping at their ends at 31 and being riveted together at 38. Lugs 33h are riveted at 34h to the sections 36 and carry cams 3Ib corresponding to those at 3|. The dogs in this form are also cylindrical and are designated 2 Ib and are suspended by springs in the form of wires at 25h corresponding to and functioning like those at 25 and 25a, and being fastened in place by screws at 2Gb. Such wires 25h pass through openings 21 in the upper ends of the dogs 2lb removably. Expansive springs 39 occupy recesses in the collar I9h which are under compression and engage the sections 3f, frictionally holding the latter against accidental turning or rotation.
